Fluorescein disodium salt (Uranine) is a highly efficient functional fluorescent dye and tracer utilized globally. In hydrological and environmental engineering, it serves as an unparalleled water tracer for mapping underground watercourses, detecting dam leakages, and evaluating water flow paths due to its intense green fluorescence even at trace levels. Industrially, it is widely formulated into central heating systems, boilers, automotive anti-freeze liquids, and hydraulic fluids for rapid leak detection. In the biomedical field, it is a critical diagnostic reagent utilized in ophthalmology for corneal injury staining, contact lens fitting, and intravenous fluorescein angiography (FA). It is also commonly used as a sea rescue marker for ocean distress visibility.
